0–100, higher is better. How it is calculated

SIX is a leading Swiss financial market infrastructure provider connecting financial markets with infrastructure, data, and services. The website presents a professional and comprehensive digital presence, offering multiple secure portals for various financial services including stock exchange, securities services, banking, and financial information. The company targets financial institutions and market participants, positioning itself as a critical player in the Swiss and international finance ecosystem. Technically, the website uses modern technologies including Adobe Experience Manager CMS, JavaScript frameworks, and integrates marketing and analytics tools such as Marketo and Google Tag Manager. Privacy compliance is well addressed with a OneTrust cookie consent mechanism and GDPR indicators. Security posture is strong with HTTPS enforced and secure login portals, though explicit security headers and vulnerability disclosure mechanisms are absent. WHOIS data is unavailable or obscured, which slightly reduces trust but is mitigated by the professional site and known brand. Overall, the website is a robust digital asset for SIX, reflecting its enterprise scale and market leadership.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

1 finding rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

SIX operates in the finance sector, providing essential infrastructure and services for financial markets, including the Swiss Stock Exchange and related clearing and settlement services. The business model is service-oriented, targeting institutional clients and market participants. The company leverages partnerships for recruitment and procurement, integrating third-party platforms like SuccessFactors and TenderTracker. The website's extensive login portals indicate a complex ecosystem of services and client segments. The brand is consistent and trusted in the financial industry, with a strong digital footprint. Growth indicators include comprehensive service offerings and integration of advanced data products. The lack of public WHOIS data suggests privacy or corporate structuring considerations.

Security posture

The website demonstrates a mature security posture with HTTPS enforced across all pages and secure login portals for sensitive services. Cookie consent and privacy compliance are actively managed. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap that could be addressed to enhance protection against common web attacks. No vulnerability disclosure or security.txt file is present, limiting transparency for security researchers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is strong but could benefit from additional hardening and transparency measures.

Recommendations

  1. Implement and publish security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  3. Provide clear incident response contact information on the website to enhance trust and readiness.
  4. Review WHOIS registration details to ensure consistency and transparency with the corporate identity.
  5. Continue to monitor and update third-party libraries and tracking tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, leveraging modern JavaScript and SVG graphics for a responsive and accessible user experience. Integration with marketing and analytics platforms like Marketo and Google Tag Manager indicates a mature digital marketing strategy. Performance is moderate with preconnect hints to key external domains. Mobile optimization and accessibility features are well implemented. The site uses structured data (JSON-LD) for SEO enhancement. Technical risks include missing security headers and potential dependency on third-party services for tracking and marketing. Overall, the technical infrastructure supports the business needs effectively with room for security improvements.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
